HiLo seatpost angle adjustment stuck?

Anyone with a Hilo, is mine seized and just needs lube and force? I knocked it out of position recently and cant adjust the saddle down at the front at all? Even with the saddle off, it seems jammed. Does the top rotate? I cant remember when fitting it to start with. Thanks

Mine was stuck, give it a tap with a mallet when you have loosened the allen bolt and it will move no probs. The top rotates as the parts that holds the saddle rails is 4 plates held together through a hole in the top of the post with a bolt.
